Why does noise reduce response to alarm calls? Experimental assessment of masking, distraction and greater vigilance in wild birds

Zhou, You; Radford, Andrew; Magrath, Robert

Description

1. Environmental noise from anthropogenic and other sources affects many aspects of animal ecology and behaviour, including acoustic communication. Acoustic masking is often assumed in field studies to be the cause of compromised communication in noise, but other mechanisms could have similar effects. 2. We tested experimentally how background noise disrupted the response to conspecific alarm calls in wild superb fairy wrens, Malurus cyaneus, assessing the effects of acoustic masking,...[Show more]
